我想从此链接中删除所有参展商名称和信息：https://asiatechxsg.com/exhibitors/ 写入 csv 文件。
我写了这个：
html = requests.get('https://asiatechxsg.com/exhibitors/').text
bs = BeautifulSoup(html)
exhibitor_links = []
for link in bs.find_all('a'):
if link.has_attr('href'):
exhibitor_links.append(link.attrs['href'])
print(link.attrs['href'])
但这些链接不是参展商链接。假设链接正确，我将迭代参展商链接中的每个链接，并从中提取名称和信息并将其存储到数据框中。但是，我也不清楚如何提取姓名和信息。我是网络抓取新手。预先感谢您提供的任何帮助。
你可以尝试：

while True:
print(page)
page += 1
data = requests.post(url, json=payload).json()
pi = data["data"]["view"]["exhibitors"]["pageInfo"]
all_data.extend(data["data"]["view"]["exhibitors"]["nodes"])
if not pi["hasNextPage"]:
break
payload["variables"]["endCursor"] = pi["endCursor"]
df = pd.DataFrame(all_data)
print(df.head(10))
